Crisis is the singular form, while crises is the plural form. Use crisis for one serious problem or difficult situation, and use crises for two or more serious problems or difficult situations.
People often search for “crisis or crises” because the plural form looks unusual. Many English nouns simply take ,s or ,es, so it may seem natural to write crisises. However, crisises is incorrect in standard English. The correct plural is crises.
This difference is important in everyday English, business writing, academic work, news reports, and formal communication. Knowing which form to use can help you avoid a common grammar mistake and make your writing clearer.
For example, you can say:
- The company is facing a crisis.
- The company has faced several crises.
The meaning is easy once you remember one simple rule: one crisis, more than one crises.

Definition and Meaning of Crisis or Crises
What Does “Crisis” Mean?
Crisis is a noun used for a serious, difficult, or dangerous situation that needs attention or action.
A crisis can happen in many areas of life. It can involve a person, family, company, country, organization, or community.
For example:
- The business is facing a financial crisis.
- She went through a personal crisis.
- The country is dealing with an energy crisis.

Words such as a, one, this, and that can help you identify the singular form.
Examples
- A crisis can develop quickly.
- One crisis affected the entire department.
- This crisis needs immediate attention.

Compare These Sentences
Singular:
The country is facing a financial crisis.
Plural:
Several countries are facing financial crises.
The first sentence discusses one situation. The second discusses multiple situations.
Why Is the Plural “Crises” Instead of “Crisises”?
This is one of the biggest reasons people search for crisis or crises.
In English, many nouns form their plural by adding ,s or ,es:
- book → books
- class → classes
- box → boxes
Because of this pattern, someone may assume:
crisis → crisises
But crisis comes from an older Greek and Latin word pattern. Its traditional plural form is crises.
The same type of change can be seen in other English words:
- analysis → analyses
- thesis → theses
- hypothesis → hypotheses
- diagnosis → diagnoses
- crisis → crises
So you should learn crisis → crises as a word pair.
Incorrect and Correct
❌ The country faced several crisises.
✅ The country faced several crises.
❌ The company is dealing with two crisis.
✅ The company is dealing with two crises.
❌ They are experiencing a crises.
✅ They are experiencing a crisis.
The Origin of Crisis or Crises
The word crisis has a long history. It comes from the Greek word krisis, which was related to judgment, decision, and a turning point.
The word later entered Latin and then English.
Historically, crisis was strongly connected with medicine. It could describe an important point during an illness when a person’s condition might change. In other words, it was a decisive stage.
Over time, the meaning became much broader.
Today, crisis can describe serious situations in many areas, including:
- business
- politics
- finance
- health
- family life
- education
- international relations
- the environment
The plural crises comes from this same word history. English retained the older plural pattern instead of creating the regular,looking form crisises.
This is why the spelling may look unusual to modern English learners.
Crisis and Crises Have Different Pronunciations
The two forms also sound different.
Crisis is pronounced approximately:
CRY,sis
Crises is pronounced approximately:
CRY,seez
So the difference is not only written. The ending sound changes as well.
British English vs American English Spelling
There is no spelling difference between British English and American English for crisis and crises.
Both varieties use:
crisis for one
crises for more than one
Comparison Table
| Feature | British English | American English |
| Singular | crisis | crisis |
| Plural | crises | crises |
| Incorrect plural | crisises | crisises |
| Singular pronunciation | CRY,sis | CRY,sis |
| Plural pronunciation | CRY,seez | CRY,seez |
| One situation | a crisis | a crisis |
| Multiple situations | several crises | several crises |
British English Example
The government is dealing with a serious economic crisis.
American English Example
The government is dealing with a serious economic crisis.
Both sentences use exactly the same spelling.
For multiple situations:
Several economic crises affected different industries.
Again, the spelling is the same in both varieties.
Is “Crisis” More Common in British or American English?
Neither spelling belongs exclusively to British or American English.
Crisis is standard in both.
Crises is also standard in both.
The choice depends on number, not region.
This means you do not need to change crisis to another form when writing for an American audience, and you do not need a different spelling when writing for a British audience.
The same rule also works well for international English.
Remember
US English: crisis → crises
UK English: crisis → crises
International English: crisis → crises
The important question is not “Which country am I writing for?”
The important question is:
“Am I talking about one crisis or more than one?”
Which Spelling Should You Use?
Choosing between crisis and crises is simple once you know if you are talking about one situation or more than one.
Use “Crisis” for One Situation
Use crisis when you are referring to a single serious problem or difficult situation.
Examples:
- The company is facing a crisis.
- The country is going through an economic crisis.
- She experienced a personal crisis.
- The team must respond to the crisis quickly.
- This crisis could affect many people.
Words such as a, one, this, and that usually help show that the noun is singular.
Use “Crises” for Multiple Situations
Use crises when you are referring to two or more serious problems or difficult situations.
Examples:
- The company has faced several crises.
- Many countries have experienced economic crises.
- The report examines different financial crises.
- These crises affected the global economy.
- Organizations need plans for dealing with multiple crises.
Words such as many, several, multiple, different, and various usually indicate that you need the plural form.
A Simple Way to Remember
Think of the number before the word:
One crisis
Two crises
Three crises
Many crises
Never write:
❌ Two crisises
Write:
✅ Two crises
Common Mistakes with Crisis or Crises
Because crises does not look like a normal English plural, it is easy to make mistakes.
Mistake 1: Using “Crisises”
This is the most common spelling error.
❌ The country experienced several crisises.
✅ The country experienced several crises.
The correct plural is crises, not crisises.
Mistake 2: Using “Crises” for One
❌ The company is facing a financial crises.
✅ The company is facing a financial crisis.
The word a tells us that the noun must be singular.
Mistake 3: Using “Crisis” After a Plural Number
❌ The company faced three crisis.
✅ The company faced three crises.
Because three refers to more than one, the plural form is required.
Mistake 4: Writing “These Crisis”
❌ These crisis created serious problems.
✅ These crises created serious problems.
The word these is plural, so crises is needed.
Mistake 5: Writing “Many Crisis”
❌ Many crisis can happen at the same time.
✅ Many crises can happen at the same time.
Many is used with plural nouns.
Mistake 6: Thinking “Crises” Is a Different Word
Some learners think crisis and crises have completely different meanings.
They do not.
Crises is simply the plural form of crisis.
Compare:
The company faced one crisis.
The company faced several crises.
The basic meaning stays the same. The number changes.
